Specification of Letters Patent.

Application filed September 27, 1909. Serial No. 519,688.

To all whom it may concern:

Be it known that I, EVERARD H. BoEoKH, a subject of the King of England, residing at Toronto, inthe Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Monoplanes; and I do hereby declare the following to be a full, clear, and exact description of the invention,.such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an aeroplane and more particularly to the class of monoplanes for aerial navigation.

The primary object of the invention is the provision of a mono lane in which the main plane thereof is ormed at opposite side edges with upwardly and inwardly curved flanges which latter serve to catch the air righting the monoplane durin its flight and also to overcome di ping o the same to either side while lifted in the air.

Another object of the invention is the provision of a monoplane in which there are disposed, beneath the main plane at opposite sides of the suspended main plane, side balance planes, which latter assist with the .adj ustable tail wing or plane in effecting the ascending or descending of the mono lane and also control the distance of flight t ereof relative to the earth.

A further object of the invention is the provision of a monoplane in which there is ormed at its forward end a breast lane, the same being intersected by a center card or keel which latter is acted upon by the air, during course of flight to maintain the monoplanes steady and. preventing unneccessary side dipping of the same.

A still further object of the invention is the provision of a monoplane in which the air resisting qualities have been reduced to a minimum, thus increasin the buoyancy and also enabling the .attalnment of high speed with the least possible motive power.

In the drawings accompanying and forming part of this specification is illustrated the preferred form of embodiment of the invention, which to enable those skilled in the art to carry the invention into practice,

will be set forth at length in the following detail descri tion, While the novelty of the invention wi 1 be pointed out in the claims succeeding the descriptlon.

It is to be understood of course that changes, variations, and modifications may be made such as come properly within the scope of the appended claims, without departing from the spirit of the invention or sacrificing any of its advantages.

In the drawings :-Figure l is a side elevation of a monoplane constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a bottom plan view. Fig. 4 is a front elevation with the propeller removed. Fig. 5 is an enlarged front elevation of the side balance planes and their operating levers with the connections between the same.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings by numerals 10 designates generally a skeleton frame structure comprising upper and lower side rails 11and 12 the latter being of greater length than the rails 11 to extend a distance rearwardly thereof and these upper and lower rails are connected by outwardly diverging spaced strips 13, while the upper rails are united-by spaced cross ribs 14, and the lower rails by cross strips 15, so as to form a unitary frame structure. This framelO, is suspended centrally from a main lane 16, the same being of substantially elliptical shape with straight opposite side edges 17, the latter having formed throughout their length with upwardly and inwardly curved converging flanges 18, the urpose of which will be hereinafter more fu y described.

Fixed near the forward end and to the bottom of the main frame 10, is a breast plane 19, the same bein rearwardly and downwardly so as to cause the raising of the upper end of the frame for lifting it into the air when started in motion for the u ward flight of the device.

Exten ing from the forward end of the frame 10 to a distance removed from its rear end and secured to the bottom thereof is a center board or fin 20, the said board being beveled toward its forward end so as not to impede the forward travel of the frame when navigating in the air.

7 Mounted in the frame 10 is a drivin engine 21, the latter being preferably 0% the fourcylinder type and to its driving shaft 22, is connected the main propeller shaft 23, by a knuckle or ball and socket joint 25, and this propeller shaft 23 extends forwardly a distance beyond the front of the frame and Patented Aug. 9, 1910.

slightly curved has fixed to its outer free end a bladed propeller wheel 26 which may be of any well known type for effecting the advancement of the machine. Upon a standard 27 within the frame is pivotally mounted a. raising and lowering lever 28, one end of which has suitable connection with the propeller shaft so as to enable it to be vertically adjusted. This lever. 28 carries the usual spring controlled locking pawl 29 engaging a toothed segment 30, so that the said lever 28, may be locked for holding the propeller shaft in its adjusted position. I I

I Beneath the main plane 16 and extending outwardly from opposite sides of the main frame 10 are skeleton bridge frames 31, in vertical u rights 32 of which are pivoted horizontal y. disposed swinging side planes 33, the latter being adapted 'to'balance the device and also to assist in guiding it in ascending and descending courses. Centrally of and near the rear edgesof the side balance planes 33 are connected cables 34, and 35, the same being trained over pulleys 36, and suitably connected to throw levers 37, the latter being pivoted to toothed segments 38, which are engaged by spring controlled locking pawls 39, carried by the throw levers 37, so as to lock the same in adjusted position and by means of these levers 37, the side planes 33, may be independently adjusted to the required degree; 1

Secured to the bottom of the frame 10 in over the ground for a distance when starting and stopping the monoplane.

At the rear of the main frame and rising from the lower side rails 12, thereof are brackets 42, towhich latter is pivoted a tail plane 43, the pivot of which has connected thereto brace pieces 44 depending from the upper rails 11 of the frame and this tail plane is adapted to swing on its pivot vertically and to accomplish this there is connected to the same at opposite edges cables 45 the lat-ter being trained over pulleys 46 and also connected to a throw lever 47 pivoted to a segment 48, which latter is engaged by a locking pawl 49 carried by the lever 47 to lock the same in adjusted position.

In rear of the tail plane is a rudder or guide plane 50 the latter mounted for horizontal swinging movement upon a vertical pivot 51, journaled in the main frame. Sintably mounted forwardly within the main frame is a steering shaft 52, havin the usual steering wheel 53 fixed thereto and also connected to this steering shaft is a cable 54, which latter is trained over pulleys 55, and has connection with the forward end. of the rudder or guide plane 50, so that upon manipulation of the steering wheel the said rudder or guide plane may be swung horibe directed upward so that bythe main plane 16, the machine willbe lifted and held buoyant in the air, The elevat on [of flight of the machine will be controlled the tail'plane 43 which latter is under the control of an operator positioned within the main frame of the machine. Thisop'erator 33 during the flight of the machine. It being understood of course that the guide plane 50 is actuated for (.lli'BCtlllgtllB machine in a. predetermined course while suspended in the air. v I I A great importance laid upon the upwardly and inwardly curved flanges at onposite end edges of the main plane 16,, for

the reason that these flanges serve to grip the currents of air during the travel of the machine so as to prevent side-wise dipping ofthe same or in other words these flanges a will be acted upon by the air currents to bring the machine into what might be termed a righted position should it dip or tilt to either side. 'Attention will be particularly called to the disposition of the center board 20 whichcacts as a keel to steady the monoplane while at flight and thereby overcome wabblin or irregularmovements to the same while heing advanced during its suspension in the air.
